There looks to be a bug on Monday.com Mac App when running Adobe CC (verified on Adobe Illustrator 2020 v24.1 and Adobe Photoshop 2020 v21.1.1).

With Photoshop/Illustrator and Monday.com apps running, you are unable to use the shortcut to zoom in on Adobe apps (Apple & +). As soon as you quit Monday.com the functionality returns to Photoshop/Illustrator as normal.
